Description

Pneumatic installations for transportation of granular, for example, abrasive material are known, including in their HHPISM; acceleration pipeline and separating line.

However, such nneumatic installations do not give the required degree of purification (; bulging materials from ache without crushing them.

In order to better dedust the material without crushing it in the described pneumatic installation, the tracing pipe is made from the side holes of the hyperexia to exit from 1) the working air. The separator is equipped with a plate in the chain part, non-opening1, it has a clamp-type ophthalmic chamber located along the collar line, forming a collar space at the bottom with a wall on the outside wall of the pipeline;

FIG. Figure 1 is a diagram of the entire nneiimatic setup; pa |)) pg. 2 - transeptorpuyuschey pipe-line and sedimentation chamber in the natural directional section; pas figs. 3 is a cross-section of the sediment chamber.

Pneumatic installation consists of a loading bucket (1), a transporting pipeline (2), a partition-saddle (3), a blind (4) and a fan (l) of high pressure.

From the bulk material, the bulk material enters i the hermetically sealed chamber (6), from where it is sucked up into t) yGm1P1) 01; one (2). transporting the mother; 1l to the separator-precipitator (3). In the liclixHiM end, the pipeline (2) has side openings (1 service unit to exit the worked out air). A flange (8) is welded over the side walls of the pipeline (2) welded sideways (9) ). Shut off by rombo1 plate): (10); ne) the farmshire part of the section of the settler is divided by the partition of the camp (11) and closed by the kooh (12). On the other side of the splitter, a splitter of the pilot bridge (13) with a downstream channel (14) to exit the || Ch1center 11 cbiiiyneio material. At the upper end of the pipeline (2), the molar (8) corresponds in size to the inner cylindrical chamber (9) and it is different, but it is somewhat narrower and has a circular opening with the walls of the central chamber.

Half of the day is the discharge of air drawn in by the fan (5). The dead material is attached to the chambers of the chamber (6) but to the pipeline, strikes the breaker plate (10), separates from the dust and falls into the shelf (8). from which it is then poured into a cone-shaped presme (13). The exhausted air from the pipeline into the side holes of the pipeline, in its further movement to the cyclone (4), washes seypayu1; iyse shelf (8) used to clean it from ache. Thus, the air flow, in addition to transporting the particulate material, is also used to dedust it.

Subject invention

A pneumatic unit for transporting and dedusting granular material, for example, abrasive material, including a transporting, accelerating pipeline and separator-precipitator in its ingressing circuit, so that, in order to better deplete the material, crushing it the pipeline is made with lateral openings at the end for the exhaust air to exit, and the separator is provided in the central part of the withdrawal with a discharge, covering the cylindrical located coaxially with the pipeline battening chamber defining a bottom annular irostranstvo fortified with etenke on the outer pipe above its lateral openings shelf skatyvayuschegos for dedusting waste material from the shelf vozluishym stream.
